Abstract

A process for the treatment of a continuous or perturbated stream of liquid material, which process comprises passing the said stream of liquid material through a zone in which at least two plasma arcs are coupled at the surface of the liquid stream in order to raise both the bulk temperature of the stream and the temperature of the outer surface of the stream of material, thereby to effect thermal and/or chemical treatment of the stream.
